Common uses
Parachuting is performed as a recreational activity and a competitive sport. It's widely considered an extreme sport due to the risks involved. In 2018, there were 3.3 million jumps in the US. Modern militaries utilise parachuting for the deployment of airborne forces and supplies. Special operations forces commonly employ parachuting, especially free-fall parachuting, as a method of insertion. Occasionally, forest firefighters, known as "smokejumpers" in the United States, use parachuting as a means of rapidly inserting themselves near forest fires in especially remote or otherwise inaccessible areas.
Manually exiting an aircraft and parachuting to safety has been widely used by aviators (especially military aviators and aircrew) and passengers to escape an aircraft that could not otherwise land safely. While this method of escape is relatively rare in modern times, it was occasionally used in World War I by German military aviators, and utilized extensively throughout the air wars of World War II. In modern times, the most common means of escape from an aircraft in distress is via an ejection seat. Said system is usually operated by the pilot, aircrew member, or passenger by engaging an activation device manually. In most designs, this will lead to the seat being propelled out of and away from the aircraft, carrying the occupant with it, by means of either an explosive charge or a rocket propulsion system. Once clear of the aircraft, the ejection seat will deploy a parachute, although some older models entrusted this step to manual activation by the seat's occupant.
